For starters,
Archer can use onli bow/crossbow respectively.
Assasin can onli use claw.
Bandit can onli use daggers or cutters for their skills.
Dragon Knight cant use single hand sword for their skills.
Pala and Fighter cant use spears for their skills.
Mages can use one-handed swords for their skills
So how can we make a weapon for all jobs to use?
And to make a custom weapon, we have to dissect the .wz files, draw sprites, fit the weapon in the game. If you wish to draw the sprites one by one, by all means make one for the server and you will be rewarded.
Sorry for the disappointment
